Title: Improvements in iron rod bending devices
IPC: B21D11/12
Filed: 1926-04-01
Abstract: 259,126. Lorenz, H. April 1, 1926. Rods and bars.-Iron rods for use in reinforced concrete ceilings &c. are cranked and formed with hooks on the ends by an apparatus consisting of a shaped base plate co-operating at one end with a clamping plate, to which is pivoted a shaped T-bar for cranking the rods, the horizontal flange of the bar having an aperture through which the rod is passed prior to forming the hookends by moving the bar on its pivot. The work is clamped between a wrought-iron bar plate a and a plate f separated therefrom by interchangeable washers g. To the plate f is pivoted at h a shaped T-bar i provided with a handle k. The hooks on the ends of the rods are first formed by passing the rod through an aperture n in the flange m and then moving the bar on its pivot into the position shown in Fig. 5. The rod is removed laterally and the tool then swung round and the rod then cranked by bending it between the bar i and base plate. The rods are previously arranged in position in the ceiling, the hooks at one end of all the rods being formed first and the parts then cranked in turn. The tool may then operate similarly on the other end of the rods. The plate f and lever i may have blades o for shearing the rods. In a modification, Fig. 3<a>, a cast steel or malleable cast-iron base plate a with an integral plate f is used a slot being provided to receive the work. The apertured flange of the bar may be made continuous or in two parts.

Abstract: Carbonaceous materials, particularly cycloparaffin oils, are hydrogenated with hydrogen under pressure preferably in the presence of a catalyst, e.g. manganese bronze, the temperature of the reaction being maintained below 20 DEG  C. by the action of a cooling agent. Oil is admitted through a pipe 13 to an insulated reaction chamber 1 filled with manganese bronze wire.  Hydrogen is pumped in through a valve 5 and a pipe 6 until the pressure reaches 25 atmospheres, the pressure being finally increased to 200 atmospheres by pumping in more oil through a valve 14.  The chamber 1 is maintained at 15-20 DEG  C. by passing brine through a cooling coil 7.  After a period of three hours the products are pumped to a still heated to 300 DEG  C. to distill off the light fractions or these may be obtained as described in Specification <PICT:0399487/III/1> 363,051.  About 75 per cent of the oil is converted into a mobile spirit boiling at 35 DEG  C.

Abstract: 440,256. Elastic rubber threads. SHEPHERD, T. L., 7, Park Lane, London. March 21, 1934, No. 8847. [Class 120 (iii)] An elastic rubber thread comprises a core b, having its surface slightly roughened, knurled or grooved and covered with a coating a which is insoluble or is rendered insoluble in water ; the coating may be rendered insoluble after application and may be consolidated on the core by rollers. Two or more of the threads may be twisted together, comminuted material may be suspended in the coating and, when threads are being twisted together, additional comminuted material may be supplied at the point of twisting. The comminuted material may be dyed and the outer skin of the coating may be removed or dissolved in parts to give the thread a speckled appearance. The thread may also be wound with a destructible helical winding which has the effect of substantially destroying the elasticity of the thread and, after the thread has been woven into a fabric, the winding may be destroyed by chemical or heat treatment.

Abstract: 721,481. Endless scraper conveyers. MINING ENGINEERING CO., Ltd. March 26, 1953 [April 7, 1952], No. 8874/52. Class 78(1). In a scraper chain conveyer of the kind having a framework composed of end-to-end connected upper and lower pan sections, one end of a pan carries at one side locking means including a movable member engaging lugs protruding from adjacent pans in both upper and lower rows, and at the other side of that or another pan in the same row is provided a pocket adapted to receive lugs protruding from adjacent pans in both upper and lower rows to lock them together. As shown, each top pan consists of a base 1 and goaf-side 4 to which is detachably secured a face-side plate 3, each of these parts having fixed thereto angles 15, 16 respectively to trap the scraper chain. Alternatively an untrapped scraper chain trough may be used of one-piece construction. The side members each have a projection 12 at one end and a projection 12a at the other. The lower pans 2 have projections 9 mounted on their sides at one end only, the other end having a casting 7 on the goaf-side and a casting 8 in which slides a captive locking bolt on the face-side. The casting 7 is formed with two pockets, a shallow one in which the lug 12 on the goaf-side of the corresponding upper pan can be slid sideways, and a deeper one in which first the goaf-side lug 9 of an adjacent lower pan is slid sideways and then the goaf-side lug 12a of an adjacent upper pan is slid sideways. Corresponding open slots are formed in the casting 8 so that the corresponding face-side lugs 12, 9 and 12a of the corresponding upper pan, adjacent lower pan and adjacent upper pan respectively can be dropped after engagement of the goaf-side lugs in the casting 7. The locking bolt is then moved into locking position to lock the structure against both longitudinal and vertical relative movement of the pans. To prevent lateral movement between upper and lower pans, downwardly projecting lugs 18 are provided on the upper pans at each side to engage with slots formed by brackets 17 secured to the lower pans. Specification 698,263 is referred to.

When handles 22 on the rear bay are rotated upwardly, the front bay closes in towards the rear bay and cam members 14, 15, Fig. 3, are rotated to drive the front bay upwards so that the pins 34 engage and deflect the springs 16. Pins 50, 52 on the front bay engage in latch members 20 on the rear bay. The front bay 30 includes an aluminium frame comprising top and bottom pieces 80, 82, a centre piece 84 and side pieces 86, 88, and a lower stainless steel stressplate 61, said frame accommodating four panels 72, 74, 76, 78 moulded of phenolic resin or dialkyl phthalate.

The space between the surfaces and the panel edge is filled with a thermosetting plastics material such as epoxy resin, 96, as shown, to bond the panels to the frame. In an alternative embodiment, Fig. 11 (not shown), the frame 162 is composed of two identical halves 164, 166 fastened together by screws and/or thermosetting plastics material to captivate the panels between the frame halves. In assembly, the frame is located in a jig, Fig. 7 (not shown), having locating means for registering with panel apertures, a bead of the thermosetting plastics material 96 is deposited in the recess 94 around the frame, the panels 72-78 are positioned in the frame under control of the locating means to engage the bonding material 96 which then flows to fill the recess 94, and the bonding material is allowed to set. In further modifications of Fig. 10, shown in Figs. 12-14, Fig. 15, Fig. 16, Fig. 17, Fig. 18, Fig. 19 (not shown), the internal peripheral recess presents several surfaces spaced from the panel edge, the spaces therebetween being filled with the thermosetting bonding material. In the modification of Figs. 20, 21 (not shown), first bonding material is deposited in part of the recess, the panels are positioned and the material allowed to set, then further bonding material is deposited in the remainder of the recess. Pins may also be inserted to secure the panels to the frame.
